I wrote a presentation of a model of personal responsibility for social calamities. It gives a way of identifying the people must culpable - the ones who are willing to make sacrifices in order to make the calamity happen and pull it all together - who desire it, recruit others and justify it. The idea is that a calamity requires a dedicated learner to make it happen. The next most culpable are the creative workers, the organizers who do at least one of those three - desire it, recruit others or justify it - typically for ulterior motives. The model came out of a historical study I made.
